Prime Minister Narendra Modi chaired a high-level meeting on March 22 to assess the current COVID-19 situation in India. During the meeting, he urged officials to take necessary precautions, such as wearing masks, to prevent the spread of the virus.

Additionally, the Prime Minister emphasized the need to enhance genome sequencing efforts in order to detect and monitor new variants of the virus.

Modi directed officials to "enhance whole genome sequencing of positive samples with the designated INSACOG Genome Sequencing Laboratories", the Prime Minister's Office (PMO) said in a release, adding that the measure is aimed to "support the tracking of newer variants, if any," and ensure "timely response".

The review meeting, chaired by Modi, was called amid a rise in the daily COVID-19 count in the country. The officials briefing the prime minister noted that an average of 888 daily cases were reported in the week ending March 22, at a positivity rate of 0.98 percent.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
